Specification of Letters Patent.

Application filed January 80, 1906. Serial No. 243.447.

Patented April 9, 1907.

To all whom it may concern:

Be it known that'I, WIL'HELM SCHWARZ, engineer, a subject of the Grand Duke of Baden, residing at Zahringer Allee, Pforzheim, Baden, German Empire, have invented new and useful Improvementsin Metallic-Hose-Winding Machines, of which the following is a panying dra s, in which-v Figure 1 is a front elevation, Fig. 2a side elevation, Fig. 3 a rear elevation, and Fig. 4 a horizontal section, of the machine.

The band of given cross-section, which is to'be wound to form a hose, is taken from the reel 1- and passes over a suitable guide 8 to the winding-spindle a, onto which it is pressed -head I) on rotation of the said spindle. T e bottom of the latter is secured to a disk 0, which rotates in a vertically-traveling slide d and can be turned by. two vertical rods e, passing through the disk 0, which disk can reciprocate on the rods. 7 The slide (1 travels on the vertical guide-bars g, and its weight is e ualized by a (Not s own in the drawings.) On rotation, of the disk 0 by the rods e the spindle a revolves likewise, and through the rolling or winding up of the band at an angle corresponding to the width thereof the spindle is drawn upward by the hose in the course of formation. The rods e are secured at both ends to a central pin, the bottom pin being rotated b the toothed gearing h, driven by the vertical shaft f. At the top end of the latter is a similar toothed gearing 7, connecting the spindle with the winding with the s indle a, rendering distortion or twisting of the finished hose imppssible. This windi apparatus consists of a drum Z, mounted in orizontal bearings in a frame It, turning on a vertical axis. By reason of a spring, the drum 1 has the tendency always to turn in the direction necessary for winding up the hose. The size and strength of the spring in the barrel n are so selected that on completion of the hose the tension of the spring is practically exhausted. In winding t e hose off the drum Z the barrel n is wound up again. The shaft f may be driven from the countershaft 0, which in its turn is driven by the pulley p and carries also two other belt-pulleys and g, which, by means of open and crossed belts, transmit the motion to the fast and loose pulleys t t, mounted on the shaft 11.. The rotations of the latter are transmitted to the vertical shaft f by means of bevel-gearings.

By suitable shifting of the belts of the pul leys q t and g t the winding apparatus can be stopped in its advance motion and then caused to rotate in the reverse direction and then this procedure reversed again. For this purpose the belt-forks are mounted on bars '0 'v, of prismatic cross-section, slid horizontally by grooved cams w w, which are only turned when a change of motion is desired. The cams are driven by means of toothed gearing y, driven by the shaft 2, on the one end of which are mounted a fast and a loose pulley 2, driven by a belt 3, passing around a pulley 4, mounted on the shaft 0. At the other end of the shaft 2 is a pulley 5, which by means of the belt 6 periodically drives the pulley 8, mounted on the shaft 7 at the bottom of the machine. The slide (1, already referred to, is secured to a belt 9, the bottom part of which passes over a pulley 11, mounted on the shaft 7, while the top part passes over a pulley 11, mounted in a verticallymovable frame 10. Ordinarily the belt 9 is so loose that the slide d can be readily drawn upward by the spindle a. The frame 10, however, is acted upon by a lever 12, one end of which engages in a groove or recess in the cam 1v, connected to the cam w, whereby on rotation of the cam a: the lever lifts the frame 10, and thus stretches the belt 9. The fork 13 for the belt 3 is mounted on a horizontal bar 14, connected by bell-lever gear 15 16 with the counterweighted reversing-levers 17 18, which project into the path of the slide d.

Normally during working the belt 9 is Jot-sag so that the slide d can move freely in the upwarddirection and the'cams w w and shaft 2 remain at rest. When the slide (1 attains its highest position, in which the spindle a is fully Wound, it strikes against the lever 18, which by means of the bell-lever 16 moves the bar 14 in such manner that the fork 13 throws the belt 3 from the loose onto the fast pulley 2. In this manner the camdisks w w are set in rotation, whereby the belt-shifting rods 22 'v' are actuated and the gear 9 t g It thus reversed. The winding apparatus will thus first stop, whereupon the reverse motion commences. The pulleys 5 8 and the lower pulley 11 rotate on the belt 3, slipping onto the fast pulley 2; but the belt 9 itself does not at first-rotate, since the lever 12 has not yet left the groove in the cam 11;, so that the upper pulley 11 still occupies its lowermost position. On rotation of the came disks w w in the moment in which they bring about reversal of the machine the raised part of th the latter is caused to swing out and lift the frame 10. The result of this is that the upper pulley 1 1 is raised and the belt 9 stretched. Owing'to the friction, the belt will now be driven by the lower pulley 11 and the slide (1 drawn downward, so that the spindle a will be drawn out of the hose, loosened through the backward rotation. On completion of this operation the cam-disks w w will have turned so far that they again draw back the rods 12 12, whereby the machine is again stopped and then driven in the forward direction. During the downward motion the slide d will have engaged the lever 17 from above and so turned it that actuation of the bell-lever 15 cannot take place. On the sub-' se uent upward motion 0 the slide, byreason of forward driving of the machine, the slide strikes the lever 17 from below, so that the latter now draws upon the bell-lever'1 5'and the belt 3 is again brought onto the loose pulley 2. The reversing mechanisms thus come to rest again and the machine now works in the forward direction.

The above-described arrangement has the advantage that the machine can be built vertically, as shown. Prior metallic-hosewinding machines could onl' be constructed on the horizontal system, t e disadvantage of which is that the machines re uire a great amount of space. The new mac 'ne, on the contrary, occupies but very little room despite its high capacity. This is a point of much importance in large factories, where a number of such machines are set up one beside the other. Another advantage is that a larger number of machines than hitherto can be placed under the charge of a single attendant.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
